Mine does this too...

In fact, I had already posted a thread about it and someone else had chimed in saying there's made the noise.
I'm not surprised. The packaging in the shipment box was a joke, and the phone must have been thrown around like crazy inside there.
Now that Jeremy mentions the compass, it makes sense. Last night when I opened the compass app, it gave me this weird image/notice. Don't remember what it said.
I'll have to set up a genius bar appt to get mine exchanged in a week or two when everything settles down.
